Here's why:
* Carburetors are mechanical devices. They use a series of moving parts and airflow to mix air and fuel for combustion.
* Electronic fuel injection (EFI) systems replaced carburetors. EFI systems use electronic sensors and actuators to precisely control the amount of fuel injected into the engine's cylinders.
So, what is an "electronic carburetor"?
It's actually a misnomer for a carburetor that has been modified with an electronic control system. This system might include:
* An electronic throttle position sensor (TPS): This sensor tells the control system how much the throttle is opened.
* An electronic fuel pressure regulator: This regulates the fuel pressure to the carburetor.
* A solenoid valve: This valve is controlled by the electronic system to open and close the fuel flow to the carburetor.
However, these systems are not true EFI systems. They are still fundamentally carburetors, relying on the mechanical aspects of a carburetor to mix air and fuel. While they add some electronic control, they lack the precision and flexibility of true EFI systems.
Why were these systems used?
* Cost-effective: Modifying an existing carburetor with electronic controls was cheaper than replacing it with a full EFI system.
* Performance gains: The electronic control provided some performance gains, especially in terms of fuel efficiency and emissions.
Why aren't they used anymore?
* Limited capabilities: Electronic carburetor modifications couldn't match the performance and control of dedicated EFI systems.
* Technological advancement: As EFI systems became more affordable and widespread, electronic carburetor modifications became obsolete.
In conclusion, the term "electronic carburetor" is a misnomer. It refers to carburetors that have been modified with electronic controls, but they are not true EFI systems.
